I was talking about the files in the events directory:

events/sched/sched_switch/{id,format,enable,filter}


Seems only the format file should go in, and perhaps the id.

I can keep the debug/tracing/events/* as is too, where the format and id
just call the same routines that the eventfs calls, but add the enable
and filter to be specific to ftrace.
